This is a new installation, so parts of it had not filled in with grass. Some of the seeding, done with straw mulch, a technique we do not recommend, didn’t germinate well and grow into good coverage with many grass plants. It’s best to get a really good start with good grass coverage on new installations. The root system will intertwine with the rings and grid and make for a unified strong surface. Note - If your site doesn’t have good grass coverage, then topdress with 1/4” sand and then re-seed or apply a layer of hydromulch. Older installations will require fertilization with NPK plus micronutrients to maintain a dense grass coverage.

Cantera sign with office building in the background.

It starts from the parking lot with a small pad of grass with sidewalks on either side, a mountable curb, then crosses a sidewalk at an angle to make a lane the length of the side of the building.

There aren’t enough established grass plants and the area should be reseeded for dense growth.
